回覆： Re: [twsocket] HTTP POST - SendStream With TMemoryStream
thanks F.P. I See, but if the file is more than 1 GB, That will cost my too mush disk free space,I am confuse on this problem, because I must add Form Field Value information on the Head of the data and boundary end of data.it will be work by ContentTypePost="multipart/form-data" mothod post. --- Francois PIETTE <[EMAIL PROTECTED]> 說： > > when I use Http Post Web to send file, > > if the file is bigger as 100mb. > > because content must has some FormField to post, > > I use MemorrStream write these information and > > FileStream. > > when I load to TMemoryStream it will cause my > computer > > slow to build MemoryStream, can I use other > mothods to > > resolve this problem? > > If you use TMemoryStream, then your 100MB of data is > loaded onto RAM which > can be slow.

I see,
but HttpCli.SendStrem must Write "Buf1" String before
Load FileStream, and Wirte "Buf2" String at end.
it seems will change my oringe file imformation.
Because the ContentTypePost="multipart/form-data"
I cannot only read file to Stream.
Do You have nice ideal?
Thanks.
Buf1="-7d5168231620eb2Content-Disposition:
form-data; name="fname+";
filename="+key+"\r\nContent-Type:
application/octet-stream\r\n\r\n";
Buf2=="-7d5168231620eb2--"

回覆： Re: [twsocket] HTTP POST - SendStream With TMemoryStream
hello
I try to use FileStrem, it must has Free Space to
create the same size of File,but it should be better
than TmemoryStream, if teh file is biger.
HttpCli->ContentTypePost="multipart/form-data;
boundary=---7d5168231620eb2";
Buf1="-7d5168231620eb2\r\nContent-Disposition:
form-data; name="fname+";
filename="+key+"\r\nContent-Type:
application/octet-stream\r\n\r\n";
Buf2=="-7d5168231620eb2--"
SendStream=new TFileStream("temp", fmCreate);
SendStream->Size=0;
SendStream->WriteBuffer(Buf1.c_str(), Buf1.Length());
TFileStream* ms=new
TFileStream(Filepath.c_str(), fmOpenRead);
SendStream->CopyFrom(ms,ms->Size);
delete ms;
SendStream->WriteBuffer(Buf2.c_str(), Buf2.Length());
SendStream->Seek(0, soFromBeginning);
